Patent GB-665960-A (GB)
Abstract: 665,960. Counting apparatus ; transfer mechanism. PITNEY-BOWES, Inc. Nov. 7, 1949, No. 28478/49. Class 106 (i). After a prepaid value in a postage meter has become exhausted, the meter automatically locks out and the postage printing mechanism cannot function until a new credit is set in to the counting and registering mechanism by breaking a seal 41, and operating a lock to gain access to the descending counting mechanism beneath a protective cover 27 (Fig. 7). The invention provides for free rotation of the figure wheels 10, 11, 12, 13 (Fig. 1), to the desired pre-payment value by sliding the wheels to the left to disengage the associated gears 10a, 11a, 12a, 13a, from their respective pinions 11b, 12b, 13b, which together with the well-known Geneva mechanism 10c, 11c, 12c, 13c, make up the transfer mechanism. In order to give a clear reading irrespective of the position of the units wheel 10 which indicates half unit values as shown, all the digits of the higher order wheels are duplicated and 20 toothed gears are associated with each wheel. This prevents a " half-way " position appearing in the higher order indicating windows 30 (Fig. 7), and it therefore becomes necessary to ensure that, after a prepayment value has been set in to the meter, the higher order wheels are correctly positioned to the specific digit necessary to ensure proper registration of the counting mechanism. This is effected by providing alternate differently-shaped gear teeth 17, 18, on each of the pinions 10b, 11b, 12b, 13b meshing with similarly-shaped teeth 17a, 17b, on the associated gears 10a, 11a, 12a, 13a. Thus when reengaging the pinions and gears the numeral wheels will only move back to the right to re-engage with the driving pinions when all the specific numerals are in correct alignment.

Abstract: 744,338. Autographic registers. AIRCRAFT GENERAL SUPPLIES & PETRONIC, Ltd., and BAXTER, R. Sept. 9, 1954 [Sept. 9, 1953], No. 24979/53. Class 106 (1). In an autographic register having a record strip 25 and a transversely movable voucher strip 32, the latter is advanced by means for operating a latch 14 to release a spring-loaded cash drawer 12. As shown, the latch 14 is released by depression of a finger bar 15 pivoted at 19. The bar also, through an arm 46, rocks a shaft 42 which acts through pawl-and-ratchet mechanism to advance a feed roller 35 for the voucher strip 32 so as to project that portion of the strip beneath the writing aperture through the side of the casing beyond a tear-off strip 37. At the writing aperture, the voucher strip passes beneath the record strip, the under-side of which is coated with duplicating material. Depression of the finger bar 15 also operates a counter 48. As the drawer opens, a pawl 29 advances a star-wheel 28 fast with the record-strip take-up spool, and the rear edge of the drawer rings a bell 49.

Title: Hopper feeder control
IPC: B65G53/66
Filed: 1978-09-13
Abstract: In the control of discrete material flow into a hopper (24), a vibratory feeder (6) has depending from its delivery end housing (4) a metering plate (2) which extends freely into the hopper (24). The discharge outlet (26) of the hopper (24) communicates with a venturi feeder (30). In use, the feed rate of the feeder (6) is initially set at a greater flow rate than the entrainment rate of material into the airstream passing through the feeder (30). The material builds up in hopper (24) and damps the vibration of the plate (2) and thus slows down the feeder (6) thereby reducing the discharge of material therefrom into the hopper (24). The entrainment rate of the feeder (30) gradually exceeds the flow of material to the hopper (24) and thus more of the plate (2) is uncovered thereby reducing the damping affect and allowing the feeder (6) to increase its delivery to the hopper (24). An automatic control is thus afforded. <IMAGE>

Title: Method and Arrangement for Reading Coded Information
IPC: G06V30/224
Filed: 1978-12-12
Abstract: Coded data represented by bars, adjacent ones of which are spaced by one of a plurality of different distances are decoded by forming a first series of pulses of width I such that each pulse represents a bar, and delaying the first series of pulses to form a second series of pulses. The delay e between the first and second series of pulses is such that if the distance between adjacent pulses of the first series is a then the leading edge of a pulse of the second series occurs during a pulse of the first series, if the distance between adjacent pulses of the first series is b then the trailing edge of a pulse of the second series occurs during a pulse of the first series. If an edge of a pulse of the second series does not occur when a pulse of the first series exists then the distance is a distance other than a or b. The delay is created by using two spaced read heads. The data is coded using magnetic bars e.g. on cheques. <IMAGE>
